Check for etc directory in your ess-svn directory. Is it really there?

This is actually very strange. Why the error appears when you open an R
file? It should accrue on ESS load, unless you are doing you own wizardy
in ess-mode-hook.

Most likely you didn't compile. Our Make is responsible for SVN revision
number in ess-version.

It is planned but trailing as I am overwhelmed with my personal
commitments right now, and I am also in the middle of switching jobs,
thing that consumes much more time than I expected. I have put aside
some hours for poly-mode.el (a new object oriented multi-mode) next
week. If everything goes according to plan you will have a basic version
of it by the end of the week.
